uksnatcher Posted July 23, 2014 Share Posted July 23, 2014 From Mintex:Bedding Procedure for M1144 / M1155 / M1166 1) Clean discs with brake cleaner2) Following initial brake test start with 3 – 4 light applications from 30mph down to 0mph.After these, follow the steps below according to Material.M1144: 6 / 7 medium pressure applications 70mph down to 30mphM1155: 8 / 9 medium pressure applications 90mph down to 30mphM1166: 9 / 10 medium applications 90mph down to 30mphWhen carrying out the bedding process, do not allow the brakes to drag, do not left foot brake. To do so may result in damage to, or failure of the brake system.Leave the brakes to completely cool. Quote Link to comment Share on other sites More sharing options...

xebec Posted July 30, 2014 Share Posted July 30, 2014 Hi Wim,Thanks for that and yes I did go to the Dutch Triumph Day. I did not see your Spit however I wasn't really looking for anyone in particular as there was a lot of cars there. I really should have paid more attention and looked out for you. It was a good day anyway as I spent a lot of time watching Nico Baas tuning up cars that had problems. Hopefully I will see you at future events in Belgium en Nederland...Thanks again.

WIMPUS Posted August 10, 2014 Author Share Posted August 10, 2014 Fitted my new discs and mintex m1144 pads this evening ..Followed the procedure like they said (as much is i could).And drove some more this evening and they do brake, but i get a sqeek when stopping/braking..I've used new sqeek plates and copper slip.Do then need to be run in more or .. is there something wrong ? Disc where cleaned a few times before the pads went on. Quote Link to comment Share on other sites More sharing options...
Clive Posted August 10, 2014 Share Posted August 10, 2014 Have you followed the "bedding in" process?Quote:Apply 2-3 Light Applications of the brakes at 30mph down to 0mphApply 3-4 Steady Applications of the brakes at 70mph down to 30mphLeave as long as possible to cool down.

JohnD Posted August 10, 2014 Share Posted August 10, 2014 9077 wrote:So the explanation given here is incorrect then?http://www.subaru4you.co.uk/brakes/whygrooved.shtmlYes, it is incorrect. Note: the web site where that advice appears is selling grooved and drilled discs!The only 'gas' around a properly bedded and used pad is hot air - no irony implied!So there might be some point to grooves, but holes? As each hole passes under a pad, another pad blocks the other side! Nowhere for hot air to go!And holes will weaken the disk; discs can develop cracks around holes, making the disc scrap. High level race teams that use iron discs will inspect after every race and replace at once if necessary. Grooves (IMHO) carry a similar risk, to no advantage.Squeaking - check for free movement of both pistons. If one is slow to come on, this will angle the disc and the pad. And while copperslip is often recommended, the idea is that the grease component melts off or vapourises, leaving the copper as a lubricant. Do you want melted grease on your discs?Better to use something made for the job. Here's an example, a special grease, plus some adhesive pads to go between pad and piston:http://www.ebay.co.uk/itm/MINTEX-CERATEC-LUBRICANT-GREASE-AND-4-ADHESIVE-ANTI-SQUEAL-BRAKE-PAD-SHIMS-SHIM-/251292559571?pt=UK_CarsParts_Vehicles_CarParts_SM&hash=item3a823428d3#ht_697wt_1190John (no connection with the vendor) Quote Link to comment Share on other sites More sharing options...

WIMPUS Posted August 10, 2014 Author Share Posted August 10, 2014 John, bought some of that Mintex grease, but for a lot less then in the ad you've send me ;D .Now here are some pic's from the old discs ... 1 of them has grooved in them ??) (last pic) Quote Link to comment Share on other sites More sharing options...
DougBGT6 Posted August 10, 2014 Share Posted August 10, 2014 I had adhesive pads that came with my Mintex but I thought they didn't look very substantial so I used the ordinary metal anti squeak shims and so far no squeaks! The disks I haven't fitted were grooved and dimpled, not drilled. I can see that drilled would weaken the disk and be prone to cracking through the hole. Since becoming aware of them I've noticed all sorts of OEM cars have grooved and dimpled, mostly exotic stuff, Mercs, Porsche etc. Oh and by the way Wim, your pics show far worse wear on one side of one of the disks than the other which I think indicates a sticking piston problemette.

JohnD Posted August 10, 2014 Share Posted August 10, 2014 Glad you got a bargain, Wimpus! Dimpled discs?That is just taking the mickey, exploiting vulnerable youths who couldn't pass English GCSE, let alone Applied Car Maintenance.No possible excuse even in exotic theory.BUT, the dimples will look like holes as corrosion makes them black, so, Blingtastico!And Ker-Ching, as the cash register ring out merrily!Don't be misled. The only thing better than a cast-iron brake disc is a cast iron vented disk, which work brilliantly if you habitually overheat brakes.While a grooved disc may indicate a sticking piston, it's not a reason to scrap the disc, unless it's too thin at its thinnest (<8mm).JOhn Quote Link to comment Share on other sites More sharing options...

Now the wobbly pedal is gone, but now i can push it deeper ... But noticed today the brakes seems to get better & better, will see the next few days.When i pushed the brakes not that hard it stopped like i normally should stop .. Hopefully my friend can help me one evening to rebuild the calipers and bleeding (don't want to ask my sister it again, she has done it 2 or 3 times and said she was asking money now for every times she needs to push the pedal ! ) :PJust the squeak is still there, sometimes hard and sometimes nothing..

WIMPUS Posted August 11, 2014 Author Share Posted August 11, 2014 Today i sanded the edge of the pads 45°, my friend said it could help.& adjusted the wheel bearings.So did that and all was fine it seemed .. Been to a friends house to work on his car, but needed to go after a part at my other friend nearby .. My friend noticed while he was passenger in my car a strange noise coming from the right/front side :o :-/So stopped at the side of the road to have a look.. Nothing out of place there, not odd movement or anything :oDrove on and was getting worse !So i dropped him off at his house and went home carefully .. Got the car up in the air (on my dark driveway ! , neighbours must think i'm mad ! )Got the pads out and wheel bearing was ok, so it must be the pads or something.. Got the pads in and pumped the brakes, it seemed the pistons where not getting back very well :-/So got a piece of wood and 1 pad out, pumped the brakes and pushed the piston back in with pliers (did that 3 times with each piston).Then i was time to have a drive !So planned to go on a very dark road, where you can do a bit of speed .. The roads to there i could still hear it a very small bit .Braked a few times from around 100kph to 50 kph and drove around some more.Noticed that the brakes where getting better and no squealing or odd sounds ! ;DBut when i needed to stop at a stop light ... squealing ! :BOh well, will see how it goes.. New pistons are on order ;) Quote Link to comment Share on other sites More sharing options...
junkuser Posted August 11, 2014 Share Posted August 11, 2014 An old trick for squeal was to cut little grooves at an angle across the surface of the pads at an angle.It is treating the symptom rather than the cause but may reduce the noise.May be worth a try Wim.

WIMPUS Posted August 17, 2014 Author Share Posted August 17, 2014 Well got new pistons & seals in my calipers .. Bleeded it twice now and noticed today i needed to pump twice to get a brake pedal like i did before i rebuilded them.. :oGoing to bleed them again tomorrow when i come from work with the car .Getting annoyed about it , also because i drive her daily . :B Quote Link to comment Share on other sites More sharing options...
